Definitions

  • the present invention relates to a needle device for medical use comprising a needle connected to a flexible tube and a sheath for enclosing the needle.
  • This type of device is used in various sectors of medical activity, in particular to transfuse, infuse or connect a patient to the blood circuit of an artificial kidney.
  • the flexible tube is connected to a pocket intended to collect the blood of the donor; in other cases, the free end of the flexible tube is provided with a connection element allowing the connection of the device at the end, provided with a complementary connection element, an infusion line or a line arterial or venous in the blood circuit of the artificial kidney.
  • a needle device of the type mentioned above presents a potential danger because it has been in contact with the blood of a patient who may be contaminated with various pathogenic germs (hepatitis or AIDS virus in particular) and the 'the needle, by its shape intended to pass through the tissues, is particularly suitable for inflicting wounds and, thereby, inoculating these germs.
  • pathogenic germs hepatitis or AIDS virus in particular
  • the protective member generally proposed for this purpose is the cap in which the needle is enclosed to protect the tip at the end of manufacture of the needle device, before sterilization.
  • This protective member effective as it is once in place, has however this major drawback that its installation itself is not without risk: it requires in fact that the user brings his hand closer with which he holds the cap the needle the point of which he directs towards the opening of the cap, that is to say also in the direction of his hand and we understand that, in a moment of fatigue, inattention or d nervousness, accidents can happen.
  • Another disadvantage of this protection member is that it can be removed.
  • US Pat. No. 4,676,783 proposes a protective member distinct from the cap placed on the needle before sterilization of the needle device.
  • This protective member is constituted by a sheath open at its two ends, concentric with the flexible tube.
  • the sleeve is designed to slide on the tube between two positions delimited by an annular stop formed on a connecting element from the needle to the flexible tube, which is always inside the sheath: a first position where the end of the sheath located on the side of the needle is stopped by the stop and where the needle is completely uncovered, the device with the needle then being in the position of use; a second position where the other end of the sheath is stopped by the stop, the needle then being completely enclosed in the sheath.
  • the sheath comprises a lug projecting in its inner channel to engage the annular stop in the second position of the sheath and block the sheath relative to the needle.
  • This protective member has certain drawbacks, which are particularly sensitive in many cases, of using the needle device where the needle must be inserted into a fistula or a subcutaneous vessel. In these cases, the needle must be placed as tangentially as possible to the skin.
  • the sheath described above insofar as it has a certain bulk, being concentric with the tube and where, in the position of use of the device, it extends over the tube from the base of the needle, imposes a significant angle of incidence of the needle relative to the skin.
  • this sheath prohibits the use of a gripping member of the butterfly wing type to facilitate the placement and removal of the needle in a vessel, this type of gripping member being attached to the base. of the needle on the flexible tube connection element.
  • this sheath can only be used to enclose the needle after it has been used.
  • the present invention therefore relates to a needle device comprising a sheath for enclosing the needle which is compatible with the use of a gripping member with butterfly wings, which does not affect the angle of penetration of the needle into a subcutaneous vessel and which does not expose the user to the risk of pricking himself when it is placed on the needle.
  • the invention also relates to a needle device comprising a sheath for enclosing the needle before and after use and, in the latter case, irreversibly.
  • this needle device comprises a projecting element extending laterally from the base of the needle and the sheath comprises at least one slot extending from its end situated on the side of the needle to allow movement of the sheath on the needle
  • the protruding element may be constituted by the wings folded against one another of a gripping member of the butterfly wing type secured to a connecting connecting element the base of the needle to the tube.
  • the needle device comprises a single slot extending over at least part of the length of the sheath.
  • the first locking means consist of the projecting element and a corresponding opening in the sheath communicating with the slot.
  • the second blocking means consist of the projecting element and a corresponding opening in the sheath located on the slot, the device comprising means for facilitating the introduction of the projecting element into the slot from the opening.
  • the opening of the first locking means is located, for example, on the slot, the opening of the second locking means being located between the opening of the first locking means and the end of the sheath located on the side of the needle. .
  • the opening of the first locking means is located laterally with respect to the opening of the second locking means with which it communicates by a passage, the device comprising means for facilitating the introduction of the projecting element into the opening of the first locking means from the opening of the second locking means.
  • the needle device comprises first and second slots extending over part of the length of the sheath.
  • the first locking means then comprise, for example, the projecting element and a corresponding opening in the sheath located in the extension of the first slot and the second locking means comprise the projecting element and a corresponding opening in the sheath located in the extension of the second slot, the device comprising means for facilitating the introduction of the projecting element into the first slot at the end of the slot located on the side of the needle and means for facilitating the introduction of the projecting element into the second slot from the opening of the second locking means.
  • the needle device for medical use shown in Figure 1 comprises a needle 1 connected by its base to a flexible tube 2 by means of a connecting element 3.
  • a stud 4 whose main function will be explained below, protrudes on the connecting element 3, perpendicular to the axis of the needle 1.
  • the stud 4 serves to locate the position of the bevel of the needle 1.
  • a tubular sheath 5 is passed over the tube 2 where it can slide freely. The sheath 5 is split over part of its length from its end located on the side of needle 1 (which will be called the front end, in the following).
  • the slot 6 of the sleeve 5 is widened by a V-shaped cutout 7 at the front end of the sleeve, to guide the stud 4 and facilitate its penetration into the slot 6.
  • the sleeve 5 further comprises an opening 8 located in the extension of the slot 6, of dimension at least equal to the cross section of the stud 4. The distance separating the opening 8 from the front end of the sleeve 5 is greater to the length of the needle 1. It is noted that, contrary to what is observed at its other end, the slot 6 is not widened at its junction with the opening 8.
  • the sheath is produced in a material having sufficient elasticity to open elastically when the stud 4 is forced into the slot 6.
  • FIG. 1a the device is shown in the position of use, the sheath 5 being able to be removed at a sufficient distance from the needle 1 by sliding on the tube 2 so as not to interfere with the handling of the latter.
  • the sheath 5 After using the device, to enclose the needle 1 in the sheath 5, it suffices to slide the sheath 5 in the direction of the needle 1, to present the nipple 4 in the V-shaped cutout 7 and to push the sheath 5 towards the needle 1, while also maintaining the tube 2, to engage the stud 4 in the slot 6 and slide it into the opening 8 ( Figure 1b).
  • the edges of the slot 6, which had moved apart when the stud 4 passed close. As the edges of the slot 6 are joined at its junction with the opening 8, the reverse operation is not possible and the needle 1 is therefore irreversibly blocked in the sleeve 5.
  • the needle device shown in FIG. 2 differs from the previous one by its sheath 5 which has a second opening 9 situated on the slot 6, near the opening 8, the distance separating the second opening 9 from the front end of the sheath 5 being greater than the length of the needle 1.
  • the slot 6 is widened by a V cut 10 at its two junction points at the second opening 9, to promote the penetration of the stud 4 into the slot 6 in the direction of the first opening 8 as in the direction of the front end of the sheath 5.
  • this sheath compared to that which has been previously described is that it can be used to protect the needle 1 before using the device. needle. Indeed, at the end of manufacture of the needle device, the sheath 5 is passed over the flexible tube 2 and is fitted on the needle 1, until the pin 4 reaches the second opening 9 (FIG. 2a). The needle device is then packaged and sterilized. To put the device in the position of use ( Figure 2b), the user need only take the sheath 5 with one hand, wedge the stud 4 with his other hand, and pull on the sheath to engage the stud 4 in slot 6 and slide it there until it escapes.
  • the user After using the device, the user does the opposite operation to replace the needle 1 inside the sheath 5, but he engages the sheath as much as possible on the needle 1 so that the stud 5 comes to be housed in the first opening 8 ( Figure 2c).
  • the needle 1 is then irreversibly blocked in the sheath 5 and the device poses no risk to the personnel responsible for disposing of it.
  • FIG. 3 represents a needle device whose sheath 5, like the previous one, is intended to be used to protect the needle 1 before the use of the device.
  • This sheath comprises an opening 11 located in the extension of the slot 6, to which the slot 6 is connected by widening (V-shaped cutout 12). The distance separating the opening 11 from the front end of the sheath 5 is greater than the length of the needle 1.
  • the opening 11 communicates with a second lateral opening 13, via a passage 14 running from narrowing from the opening 11 to the opening 13 so as to facilitate the passage of the stud 4 in one direction and to hinder it in the opposite direction.
  • this needle device is presented as illustrated in FIG. 3.
  • the user pulls the sheath 5 with one hand in the direction of the flexible tube 2, while maintaining the nipple 4 on the other hand.
  • the user practices in the opposite direction to bring the stud 4 back into the first opening 11.
  • he rotates the sheath 5 relative to the needle-flexible tube assembly to force the stud 4 into the passage 14 and make it penetrate into the second opening 13.
  • the reverse operation will be impossible to carry out, at least involuntarily.
  • FIG. 4 represents a needle device which differs essentially from those which have been described previously in that it is provided with a gripping member of the butterfly wing type, of a type known per se, which is intended to facilitate the implantation and withdrawal of needle 1 in a fistula or subcutaneous vessel, and to provide a stabilizing element for the device once placed on a patient.
  • This gripping member comprises a tubular body 15 fixed on the connecting element 3 of the needle 1 to the flexible tube 2, body to which two wings 16 are articulated by means of hinges 17.
  • the wings 16 can be folded one against the other (gripping position illustrated in FIGS. 4a and 4c) and they can also be deployed totally (stabilization position illustrated in FIG. 4b: a piece of adhesive plaster fixing the wings thus deployed to the patient's arm prevents the needle 1 from pivoting relative to its initial axis of implantation).
  • the wings 16 folded against each other which play the role of projecting element (used in the devices of FIGS. 1 to 3 at the stud 4) intended to cooperate with the openings of the sleeve 5 to immobilize the needle 1 inside the sheath 5, reversibly or irreversibly depending on the type of opening.
  • the sheath 5 comprises a first opening 8 situated in the extension of the slot 6, having dimensions sufficient to allow passage at the base of the wings 16. The edges of the slot 6 are joined at its junction with the opening 8
  • the sleeve 5 further comprises a second opening 9, located on the slot 6 near the opening 8, the slot 6 widening at its two junction points at the opening 9 (V-shaped cutouts 10) .
  • the distance separating the opening 9 from the front end of the sheath 5 is greater than the length of the needle.
  • the opening 8 is barred by a transverse stop 18 having a zone of least resistance at its connection to the sheath 5.
  • the stop 18 has the function of preventing the fins 16 from completely penetrating into the opening 8.
  • this needle device is as shown in FIG. 4a: the sheath 5 is fitted onto the needle 1, which it completely encloses, the rear of the wings 16 being in contact with the stop 18 and the wings themselves being pinched by the edges of the slot 6 extending between the two openings 8, 9.
  • the needle 1 can be removed from the sheath 5 to be placed on a patient. It suffices for the user to grasp the wings 14 with one hand and pull the sheath 5 with the other in the direction of the flexible tube 2, the slot 6 widened at its junction at the opening 9 allowing the wings to penetrate into slot 6 by spreading the edges.
  • the device is then in its position of use illustrated in FIG. 4b.
  • the user To remove the device put in place on a patient, the user begins by popping the stopper 18 by pivoting it outwards around its weakened area.
  • the needle device shown in FIG. 5 differs from those which have been described above in that its sheath 5 comprises not one but two diametrically opposite slots 6, 19 extending from the front end of the sheath 5
  • the sheath 5 is provided with two reinforcing elements 20 extending from its rear end to keep the two sheath halves defined by the slots 6, 19 closely approximated.
  • the reinforcing elements 20 are profiled to facilitate gripping of the sheath 5 between thumb and forefinger.
  • the slots 6, 19 are respectively extended by two openings 8, 21 dimensioned to receive the stud 4. The distance separating the openings 8, 21 from the front end of the sheath 5 is greater than the length of the needle 1.
  • V 7 widens the slot 6 at the front end of the sheath 5, while the edges of the slot 6 are joined at its junction with the opening 8. Conversely, the edges of the tent 19 are joined to the front end of the sheath 5 while a V cut 22 widens the slot 19 at its junction with the opening 21.
  • the needle 1 is enclosed in the sheath 5 in the position shown in FIG. 5a, the stud 4 passing through the opening 21 and blocking the needle 1 in the sheath 5.
  • the needle 1 can however be taken out of the sheath 5 thanks to the V-shaped cutout 22 which promotes the introduction of the stud 4 into the slot 19 when the sheath 5 is pulled towards the tube 2 while maintaining the stud 4 fixed, traction which results to let the pin 4 out of the slot 19.
  • this device therefore also comprises two types of locking means for immobilizing the needle 1 in the sheath 5 respectively reversibly before use (stud 4, opening 21) and irreversibly after use (stud 4, opening 8).
  • the present invention is not limited to the embodiments which have just been described and it is susceptible of variants which will appear to a person skilled in the art.
  • the means for promoting the introduction of the projecting element (stud 4, wings 16) into the slot 6, 17, which are constituted in the examples described by the V-shaped cutouts 7, 10, 22 widening the slot 6 to its ends could be replaced by equivalent means: the edges of the slot could thus have a constant spacing over their entire length and the protruding blocking element be provided with tapered leading edges (stud 4 of triangular cross section, by example).
  • the sheath 5 could be split over its entire length and the slot not be straight but helical.
